Abstract

According to ADS——NEUTRONIC BENCHMARK data and model offered by IAEA, the radiation dose produced by the leakage of the neutrons and the photons in the ADS'(accelerator-driven sub-critical system) proton tube were calculated with the MCNP program. The fluxes of the neutrons and the photons which directly leak out from the proton tube are large and the energy is high; the above 80% radiation dose around the proton tube at the reactor outside comes from the radiation of the neutrons and the photons in the proton tube, only a small fraction that from the reactor. A special study on the radiation shield of proton tube in ADS is essential.
